Inrush Current

The peak current flowing into a power supply the instant AC power is applied. This peak is usually much higher than the steady state input current due to the charging of the input filter capacitors. For detailed explanation: http://wp.me/p2T1XY-51

What is Inrush Current – Details explained

When AC is initially powered ON, a peak current is required to charge the empty bulk capacitor. This momentary peak is also called the inrush current. The magnitude of the inrush current varies according to the type of current limiting circuit used. S.P.S. commonly uses a thermistor to limit inrush current. The high resistance of [...]
